Sheldon: When the toupee licked my hand I screamed and hopped down the street on my remaining flip-flop.
Amy: Can I just ask?
Sheldon: No, this is a long story. Why don't we please save your questions till the end?

Howard: Our culprit is one Mr. Todd Zarnecki, 2711 Ocean View Road, Carlsbad, California.
Sheldon: The name and the address drip with evil.

Amy: Well, the first thing that comes to mind is isolating the part of your brain where the memory is stored and destroying it with a laser.
Sheldon: Hmm, no. One slip of the hand and suddenly I'm sitting in the Engineering Department, building doodads with Wolowitz.

Penny: Okay, Cat on a Hot Tin Roof is an American classic.
Sheldon: So is the McRib sandwich. I don't care for that either.

Howard: So, how do you guys want to play this?
Sheldon: Be ruthless. You tell him if he doesn't start talking, we'll register a complaint with his Internet service provider.
Raj: Sheldon, what if he gets his Internet from his cable company? He could lose his HBO and all their delightful original programming.
Sheldon: I don't care! I'm losin' it, man!

Penny: Okay, well, anyways, I brought you a day-old cheesecake to cheer you up!
Sheldon: Stale pastry is hollow succor to a man who is bereft of ostrich.
Penny: Just say thank you.
Sheldon: I thought I just did.

Howard: Whoa! Somebody's auctioning off a jewelled ostrich bridle!
Sheldon: No. Glenn's was leather. He was a simple ostrich. Is! Is, I haven't given up hope.

Leonard: So you need these people's support and you're sending them baked goods?
Penny: Yeah, they're pretty smart. Don't you think they're gonna realize it's just a bribe?
Sheldon: No, you'd think, but sometimes brilliant people can be painfully oblivious to social cues.
Penny: Thank you for pointing that out, Sheldon.
Sheldon: Anytime.

Raj: He'll have a Shirley Temple.
Sheldon: And don't be chintzy with the Shirley.

Sheldon: Penny, it's your lucky day. Three of these eggs are clearly not jumbo size. Grab your keys!

Amy: Is there anything I can do to help?
Sheldon: Yes. I want you to be in charge of our wedding. Just you tell me where and when, and I will show up with a boutonnire and close-toed shoes and a a Star Trek uniform underneath my tuxedo. That last part is non-negotiable.

Howard: Sheldon, why do you have all these unopened paychecks in your desk?
Sheldon: Because most of the things I'm planning to buy haven't been invented yet.
Howard: But there must be thousands of dollars here. Why don't you put it in the bank?
Sheldon: I don't trust banks. I believe that when the robots rise up, ATMs will lead the charge.

Amy: Hey, good news. They're inviting several Nobel Laureates to our reception.
Sheldon: Oh, great, like who?
Amy: Uh, Makoto Kobayashi.
Sheldon: Ooh.
Amy: What?
Sheldon: Well, I may have been less than kind to him about his Nobel Prize win.
Amy: Why?
Sheldon: I was jealous, angry and new to Twitter. It was a dangerous combination.
Amy: Okay, so scratch Kobayashi.

Penny: (On the phone) Mrs. Cooper, hey, it's Penny. Yeah, I think I broke your son. Hey, hold on. Talk to your mother.
Sheldon: Mommy, I love you. Don't let Spock take me to the future!

Sheldon: Pick a card, Sheldon. Now look at it and put it back in the deck. Now do you remember your card? Of course I do, I have an eidetic memory.
